Give an example of displacement reaction.

Explanation

When zine granules are added to the blue coloured copper sulphate solution, the zinc ions formed from atoms take the place of `Cu^(2+)` ions in `CuSO_(4)` and copper atoms , formed from `Cu^(2+)` ions comes out i.e. the more reactive zinc displaces the less reactive Cu from copper sulphate.
`underset("zinc")(Zn_((s)))+underset("sulphate")underset("copper")(CuSO_(4_((aq))))rarrunderset(("colourless"))underset("zinc sulphate")(ZnSO_(4_((aq))))+Cu_((s))+"Heat"`
